www: remove smsg_mime API and adjust callers

To further simplify callers and avoid embarrasing memory
explosions[1], we can finally eliminate this method in
favor of smsg_eml.

[1] commit 7d02b9e64455831d3bda20cd2e64e0c15dc07df5
    ("view: stop storing all MIME objects on large threads")
    fixed a huge memory blowup.
